I believe the good doctor presented a lot of information to all the teams and also to the press.
If Mara wants to make a case that the Cowboys got more info, it would be difficult to prove.
Here is an article on USA Today before the draft "Jaylon Smith's nerve issue still clouded, but surgeon says recovery odds 'very good'"
http://www.usatoday.com/story/sport...aylon-smith-knee-nerve-injury-draft/83416394/
Here are quotes from the article:
Dr. Dan Cooper, who is “optimistic that his knee itself will be stable and a good knee and he’ll get all his strength back. And I also think he has a very good chance of getting his nerve recovery back.”
That’s because the lateral damage stretched Smith’s nerve “enough to make it go to sleep, but it wasn’t stretched enough to be structurally elongated or visually very damaged” like more severe injuries, Cooper told USA TODAY Sports. There’s normally a one-month lag time before the nerve regrows at all, and once it begins, the rate is only about 1 inch per month.
“He’s had time for his nerve to regrow 2 inches, and the area of where his nerve was injured is 6 inches above the muscle that it innervates,” said Cooper, who’s also the Dallas Cowboys’ head team physician. “I wouldn’t really expect him to get much innervation back into that muscle for two or three more months. Then once it does – I’ve seen kids who are completely paralyzed like him on the lateral side and not able to pick their foot up at all (that) wind up being totally normal.”
